The German goalkeeper says Swansea must focus on trying to stop Benitez’s side, who are third in Serie A and also through to the final of the Coppa Italia.

“Naturally, it was disappointing to lose because we wanted to go further in the FA Cup,” said Tremmel. “We tasted success in a cup competition last season, and it would have been nice to do the same this year. But we are still in the Europa League and we have to look ahead to Thursday’s game now.

“It promises to be a great occasion at the Liberty, Napoli are having a good season in Italy and we’re under no illusions about how tough it is going to be.”
